Hunter 44001110 Adjustable Rotor 4 Inch Pop-up

Product Description

The HUNTER 44001110 is a 4-inch pop-up adjustable rotor designed for residential and commercial irrigation systems. It delivers water across a radius of 17 to 46 feet and offers 34 nozzle choices to match a wide range of coverage requirements. The rotor features a non-strippable, vandal-proof drive mechanism that protects the gear train from damage, reducing service calls and replacement costs. FloStop control allows individual head shutoff without disrupting the rest of the zone. A built-in drain-check valve prevents low-head drainage after each cycle. Licensed irrigation professionals and landscape contractors are the primary installers of this product.

The I-20 series rotor suits residential lawns, commercial turf, and mixed-planting zones. Its adjustable arc range runs from 50 to 360 degrees, with a non-reversing full-circle 360-degree mode also available. The automatic arc return feature ensures the rotor resets to the correct start position after each cycle. The 4-inch pop-up height makes it well-suited for turfgrass applications where a taller riser would be a mowing hazard or an aesthetic issue. It performs reliably in sandy soils and other variable soil conditions where uniform distribution is a priority.

Installation Notes

Installation should be performed by a licensed irrigation contractor or qualified landscape professional in accordance with local irrigation and plumbing codes. Shut off the irrigation system water supply and depressurize the lateral line before removing or installing any rotor head. Set arc and radius adjustments through the top of the rotor cap using the manufacturer-supplied adjustment tool before backfilling. Verify head spacing against the selected nozzle radius to ensure head-to-head coverage and uniform distribution.
